Mea hoʻolako honua no ka mālama ʻana i ke kaiapuni

ʻO kahi ʻenehana pololei palupalu hou a me kāna noi ʻana i ka mea insulation

Mai ka makahiki 1966, ua paʻa ʻo EM Technology i ka noiʻi a me ka hoʻomohala ʻana i nā mea insulation.56 mau makahiki mahiʻai i ka ʻoihana, ua hoʻokumu ʻia kahi ʻōnaehana noiʻi ʻepekema nui, ʻoi aku ma mua o 30 mau ʻano mea insulation hou i kūkulu ʻia, e lawelawe ana i ka mana uila, mīkini, petroleum, kemika, uila, kaʻa, kūkulu, ikehu hou a me nā ʻoihana ʻē aʻe. .I waena o lākou, noiʻO nā mea insulation i nā mīkini hoʻoheheʻe ʻia kekahi o nā kuhikuhi nui a mākou e kālele nei.

Ma ke ʻano he hanauna hou o ka ʻenehana hoʻoili DC, ʻano like ka hoʻoili ʻana o ka DC maʻalahi me ka hoʻouna ʻana i ka HVDC ma ke ʻano, aia nō ia me nā kikowaena hoʻololi a me nā laina hoʻouna DC.ʻOkoʻa mai ke ʻano hoʻololi kumu hoʻololi o kēia manawa HVDC e pili ana i ka ʻenehana commutation i hoʻopaʻa ʻia i ka phase-controlled, ʻo ka mea hoʻololi i ka hoʻololi DC hikiʻole ke hoʻololi i ka volter source converter (VSC), kahi i ʻike ʻia e ka hoʻohana ʻana i nā mea hoʻololi (maʻamau IGBT) a me ka ʻenehana modulation kiʻekiʻe. .I kēia mau makahiki i hala iho nei, ke ulu nei ka hoʻoili ʻana o DC maʻalahi i ka pae kiʻekiʻe a me ka hiki.

Ke kūlana noi o IGBT: Ua piha ʻo IGBT i ka ʻīpuka bipolar tube insulated, hiki ke hoʻopau ʻia, loaʻa nā pōmaikaʻi o ka liʻiliʻi liʻiliʻi a me ka mana maʻalahi, a hiki ke manaʻo ʻia ʻo ka CPU o ka hoʻouna pololei pololei.I kēia manawa, ua noi ʻia ʻo IGBT i ka papahana i nā huahana lawe ʻia mai, ʻo ka nui o ABB a me Siemens, ʻoiai ʻo IGBT home me ka uila kiʻekiʻe a me ka mana kiʻekiʻe ʻaʻohe huahana makua.I kēia manawa, lohi ka holomua o ka localization, ikaika ka hilinaʻi lawe mai, a ʻoi aku ka nui o ka pilikia.I ka manawa like, ʻo ke kumukūʻai o IGBT e pili ana i ka 30% o ke kumukūʻai valve.

Hiki i ka IGCT hou: No ka haʻahaʻa haʻahaʻa o IGBT ma Kina, hoʻāʻo mākou e pani i ka IGBT me IGCT.ʻO ke alapine hoʻololi, ka mana hoʻokele a me nā hana ʻē aʻe o ka IGCT kuʻuna he haʻahaʻa ia i ka IGBT, akā loaʻa iā ia kekahi mau pono i ka hiki, ka nalowale o ka mokuʻāina, ka hoʻololi ʻana a me ke kumukūʻai (ʻo ke kumukūʻai o nā huahana me ka mana like e pili ana i ka 1/2 o IGBT ).Eia nō naʻe, inā hoʻohana ʻia ka IGCT kuʻuna i ka hoʻoili mana maʻalahi o ka UHV, i ka manawa e hoʻāla ʻia ai ka IGCT, e hoʻopuka ka diode i kahi manawa hoʻihoʻi hoʻihoʻi nui, a he hopena nui ia i ka ʻōnaehana.No laila, i mea e pale ai i ka diode, ua noiʻi mākou i ka ICCT hou ma o ka hoʻohui ʻana i nā kaʻa absorption hou ma ka module IGCT kuʻuna e hōʻemi i ka hopena ma ka ʻōnaehana.

Nā noi IGCT hou: Me ka hoʻohui ʻana o nā kaʻa absorption hou, ʻoi aku ka paʻakikī o kā mākou hoʻolālā IGCT hou a ʻoi aku ka kiʻekiʻe o ka hopena hopena a me ka hilinaʻi kiʻekiʻe, no laila hiki iā mākou ke hana i nā mea insulation me ka hilinaʻi insulation kiʻekiʻe a me ka ikaika mechanical.Ke noiʻi mua nei ʻo Xd Power System Co., Ltd. i nā mea insulation no ka IGCT absorption circuit no ka papahana Yunnan Maitrei.Inā hoʻokumu ʻia ka hoʻolālā ma ka XD Power system scheme, e hoʻemi ʻia ka helu o nā modules IGCT ma kahi o 3% i hoʻohālikelike ʻia me IGBT, a ʻo ka nui o nā mea insulation he 2-3 mau manawa o ka IGBT.
